when should i buy a comp for PS2?

[mefy]

Can anyone verify if this is spot on?

"If you are a gamer, the focus should be on the graphics card, more than the cpu. For that, a strong quad will do the job. Few games use more than two or three cores, making hyperthreading and 6 core cpu's of marginal value for gaming. Today, the sandy bridge 2500K is the gamer's cpu of choice in the $200 price range. It is so good, particularly when overclocked, that a future upgrade to ivy pridge will likely not be needed to run the strongest of graphics cards. The 22nm ivy bridge follow on's to the 2500K will be compatible with the P67 and Z68 chipsets if necessary.

If, you run multi core enabled apps, then the more cores the better. It is looking like the upcoming bulldozer 8 core offerings will be good value. But, we have yet to see any benchmarks. Historically, Intel has had cpu's that are more effective per clock, so a comparison without benchmarks will be difficult.
And, a little later this year, the sandy bridge-E will give bulldozer a run for the money at the highest price range. Particularly if you value 32-64gb of ram. "
